On-Site Training - HEC-RAS Workshop for Unsteady Flow

HEC-RAS Computer Workshop for Unsteady Flow Applications


 Purpose and Background 

This seminar provides an opportunity for those with prior HEC-RAS modeling experience to use the program for modeling unsteady flow applications as well as advanced aspects of steady flow modeling. Experienced instructors will walk attendees through a number of learning modules and provide valuable hands-on experience while working with HEC-RAS software.

This ASCE On-Site Training provides an introduction to the unsteady flow component of HEC-RAS. The course lecture will expound upon unsteady flow theory, steps for developing an unsteady flow simulation, and procedures for creating a stable and calibrated model. Instructor guidance will provide techniques on modeling bridges and storage areas in the unsteady flow environment. Attendees are shown the inline and lateral weir features, which can be added in both steady and unsteady flow models.

 Workshops accompanying these lectures provide practical application experience in HEC-RAS unsteady flow modeling. New features in the latest release of HEC-RAS are also discussed as part of the class. This seminar is held in conjunction with ASCE's Environmental and Water Resources Institute (EWRI).

Seminar Instructor 

Raymond Walton, Ph.D., P.E., D.WRE, F.ASCE, is Vice President, Bellevue, Washington Office Manager for West Consultants and former Region 8 Governor. Dr. Walton has over 35 years of experience directing water resources studies throughout the US and abroad. He is a nationally-recognized expert in multi-dimensional modeling of surface water, groundwater and water quality systems. Prior to joining WEST, he worked at the Hydraulics Research Station in the UK, taught at North Carolina State University, and spent 15 years with large nationwide consulting engineering firms. He has written over 50 professional papers in the fields of hydraulics, environmental engineering, groundwater and surface water hydrology, and instructs HEC-RAS nationwide.

Martin J. Teal, P.E., P.H., D.WRE, F.ASCE, has worked with hydraulic models for more than 20 years and is currently a Vice President with WEST Consultants. His experience includes working as a hydraulic engineer for the U.S. Army Corps of Engineers and as a civil engineer for a large multinational firm in Chile. As a private consultant with WEST, he has dealt with complex hydraulic, hydrologic, and sedimentation problems. He has used computational models, such as HEC-RAS and HEC-6, as a principal tool to deal with these problems for clients in both the public and private sectors throughout the United States and internationally. His sedimentation modeling experience includes reservoir sedimentation studies of main stem dams on the Missouri River, investigation of effects of in-stream sand and gravel mining, and other studies for rivers and washes from coast to coast.
